   10  Chapter 3 Web User Interface This section describes how to access the device via the web user interface (WUI) using an Internet browser such as Internet Explorer (version 6.0 and later).   3.1 Default Settings  The factory default settings of this device are summarized below.  •  LAN IP address AP: 10.0.0.2 •  LAN IP address STA: 10.0.0.10 •  LAN subnet mask: 255.255.255.0 •  Administrative access (username: root, password: 12345)  Caution: The LAN setting default is DHCP mode, if a device connects to the DHCP network, the LAN IP will be changed by the DHCP server assigned. Technical Note  During power on, the device initializes all settings to default values.  It will then read the configuration profile from the permanent storage section of flash memory.   The default attributes are overwritten when identical attributes with different values are configured.  The configuration profile in permanent storage can be created via the web user interface or telnet user interface, or other management protocols.  The factory default configuration can be restored either by pushing the reset button for more than ten seconds until the power indicates LED blinking or by clicking the Restore Default Configuration option in the Restore Settings screen.
   11 3.2 IP Configuration  STATIC IP MODE   In static IP mode, you assign IP settings to your PC manually.  Follow these steps to configure your PC IP address to use subnet 10.0.0.x.  NOTE: The following procedure assumes you are running Windows.  However, the general steps involved are similar for most operating systems (OS). Check your OS support documentation for further details.  STEP 1:  From the Network Connections window, open Local Area Connection (You may also access this screen by double-clicking the Local Area Connection icon on your taskbar). Click the Properties button. STEP 2:  Select Internet Protocol (TCP/IP) and click the Properties button. STEP 3: Change the IP address to the 10.0.0.x (10<x<254) subnet with subnet mask of 255.255.255.0. The screen should now display as shown below.      STEP 4:  Click OK to submit these settings.
   12  3.3 Login Procedure Perform the following steps to login to the web user interface.    NOTE: The default settings can be found in section 3.1 Default Settings.     STEP 1:  Start the Internet browser and enter the default IP address for the device in the Web address field. For example, if it is the AP device default IP is 10.0.0.2, type http://10.0.0.2  STEP 2:  A dialog box will appear, such as the one below.  Enter the default username and password, as defined in section 3.1 Default Settings.    Click LOGIN to continue.

This data can be useful to assist in debugging the system.   After selecting “Start”, the page will look similar to the image above. The logging will stop after pressing the “Stop” button. If the IP address is changed or if the device is shut off, this page will give an error message if logging was in progress. To recover the session, please press the “Start” button again.   This interface takes data from an internal OS file, so intermittently; there may be management messages that show up in this log.
   47 Metric  Description  Comments  Tstamp  This is the system time of the measurement taken from the internal system clock  RxPkts   This represents the number of packets that were successfully received over 1 second intervals. Each line represents 1 second of time.   RxGain  This is the higher receiver gain value that was recorded on successfully received packets during this measurement interval. If no packets were received, this may be an invalid number. The maximum value of RxGain is 62  CRC  This is the number of CRC errors received over the 1 second measurement interval If (CRC/Rx Packets) > 10-20%, then the channel condition or link quality is poor. This is possibly due to interference, another Wi-Fi network or being too far for the current configuration to be reliable. Noise  This is the MAX receiver noise floor as measured over this 1 second interval This value is an internal noise calculation, not external. In normal operation it will vary between 20 and 70.  TxPkts  This is the number of successfully transmitted packets over the last 1 second interval.
   48 Defers  This number counts the number of times an attempted transmission was deferred due to the medium being busy.  This is helpful in determining if an environment is very busy. Defers are common in busy WiFi environments  Tout  This is an indicator of Tx packet timeout  Timeouts are not common. The Packet could not find a time slot to transmit.   Retries   This counts the number of transmission retries that have occurred over the last one second.  This is primarily due to the lack of acknowledgements from the partner device.  On the transmit side, note that the general packet flow for error is as follows:   Defer  Retry  Timeout  ShPre  This counts the number of Short Preamble Detection Errors These are very common in high throughput conditions  LgPre  This counts the number of Long Preamble Detection errors The wireless received a signal which passed the short preamble, but failed the more complex long preamble. These are less common than short preamble errors.  Rate  This is a legacy measurement for rate and is not currently used
   49 6.2 Tools – Admin This page is for administration of the user passwords.       Menu Item  Description  Notes  User Name  The user name for login Only for the login privilege  Old Passphrase  Enter the original password of the user name  New Passphrase  Enter the new passphrase    New Passphrase Again  Enter the new passphrase again It should be the same as the “New Passphrase”
